As more focus is brought to scaling up perovskite/silicon tandem solar cell technologies, it has been found that optimising the transverse resistance of interconnection leads significant quenching shunt defects in perovskite sub-cell.

With the increasing population worldwide, consumption of fossil energy is grows to be enormous [...]

Perovskite solar cells have emerged as promising photovoltaic systems with superb power conversion efficiency. For the practical application of perovskite devices, the greatest concerns are the power output density and the related dynamics under working conditions. In this study, the working conditions of planar and mesoscopic perovskite solar cells are simulated and the power output density ev...

We report on a new metal halide perovskite photovoltaic cell that exhibits both very high solar-to-electric power-conversion efficiency and intense electroluminescence. We produce the perovskite films in a single step from a solution containing a mixture of FAI, PbI2, MABr, and PbBr2 (where FA stands for formamidinium cations and MA stands for methylammonium cations). Using mesoporous TiO2 and ...

Although there has been rapid progress in the efficiency of perovskite-based solar cells, hysteresis in the current-voltage performance is not yet completely understood. Owing to its complex structure, it is not easy to attribute the hysteretic behavior to any one of different components, such as the bulk of the perovskite or different heterojunction interfaces. Among organo-lead halide perovsk...

The area of thin-film photovoltaics has been overwhelmed by organometal halide perovskites. Unfortunately, serious stability concerns arise with perovskite solar cells. For example, methyl-ammonium lead iodide is known to decompose in the presence of water and, more severely, even under inert conditions at elevated temperatures. Here, we demonstrate inverted perovskite solar cells, in which the...

Perovskite films are a promising candidate for future highly efficient and low-cost solar cells. The long diffusion length of charge carriers in the perovskite film makes its architecture fabrication seem unnecessary, while the rapid crystallization process increases the difficulty in its architecture fabrication. Here we show the fabrication of perovskite architectures through a nucleation med...

Perovskite Solar Cells In article number 2202438, Cong Chen, Dewei Zhao, Fan Fu, and co-workers report 15.1% flexible near-infrared transparent wide-bandgap (1.77 eV) perovskite solar cells with a low open-circuit voltage–deficit of 480 mV. When paired flexible, narrow-bandgap (1.24 cells, they demonstrate 23.8% all-perovskite tandem cell superior voltage 2.1 V.

To realize the high efficiency potential of perovskite/chalcopyrite tandem solar cells in modules, hydrogenated In2O3 (IO:H) as electrode is investigated. IO:H with an electron mobility of 100 cm 2 ·V -1 ·s -1 is demonstrated. Compared to the conventional Sn doped In2O3 (ITO), IO:H exhibits a decreased electron concentration and leads to almost no subbandgap absorption up to the wavelength of 1...

Hybrid perovskite solar cells have provided a steep change in photovoltaics research. They combine the key advantages of all emerging photovoltaic technologies, including: inorganic thin-film photovoltaics (high efficiency); organic photovoltaics (ease and economy of deposition and diversity of materials) and dye-sensitized solar cells (chemical versatility and architecture). For this reason, t...
